PitneyShip Pro Release Notes version 1.119.0 (January 7, 2026)
Products affected: PitneyShip® Pro
What's New
Support for USPS 6x4 IMb Labels
We’ve added support for USPS 6x4 Intelligent Mail® Barcode (IMb) labels within First Class Mail for letters and envelopes. Users can now print these labels directly from the Stamps screen, and they include tracking, which is automatically available in the History page under the USPS Stamps tab. Print settings for 6x4 labels can be managed under Stamp Options, and both sender and recipient addresses are required. These shipments are non-refundable, and no action buttons will appear in History for them. After a successful label is generated, the confirmation message includes a link to Shipment History for easy access. Additionally, the Envelope 6x4 label size option is now available in stamp settings for default printer setup.
Latest Updates
Removed multi-piece shipments for UPS and FedEx PB Rate accounts
Multi-piece shipping is now disabled for UPS and FedEx PB rate accounts. As a result, the multi-piece tab on the Create Shipping Label screen will only show Non-PB Rate carrier accounts.
